|#4 ISO bus goes directly from 4x4cm to the data link connector on obd2 port (so the scanner can talk to moto box and pull any 4x4 codes, diagnose 4x4cm)
#12 boo is brake pedal position switch input to 4x4cm, somply tap into your BOO or BPP wire, (red/lg on earlier fords, circui 810)
#16 NSS input from DTRS I believe it is a power through the DTRS switch but we can look it up. Circuit 463 rd/wh at older fords
This wire should go directly from the DTRS to your 4x4cm, there is a NSS wire at your 4r70w DTRS now very likely if not I can get you the pin number
#1 Circuit 359 SSR at pcm, sensor signal return from 4x4 dash switch to the PCM/GEM module on older fords (grey with red on older fords)
#12 VSS usually at the GEM module on older fords, grey/black
When I say "older fords" I mean older then the 03 control module, like 96-01 Explorer, Ranger, etc
So for example the VSS and SSR wires would normally come from the GEM module on a 98 explorer. On your truck I am not sure but we can map out their circuits on the older trucks and that will give you a clue as how to wire them in.
So your current engine computer does not have any vss feeds right? it is all gps? there is no speed sensor in the rear axle? wheel speed sensors?
The 4x4CM wants to see you are not moving before it will allow you to shift into 4low (below like 4mph or some crap) We might be able to just ground this wire but dont do that YET let me look it up where it would go on a 98 sploder......
